Lactose intolerance is very common in adults. It is rarely dangerous. Around 30 million American adults have some degree of lactose intolerance by age 20. 1  In Caucasians, lactose intolerance often develops in children older than age 5.  In African Americans, the problem can occur as early as age 2.
The winter flounder is one of five species in the genus Pseudopleuronectes along with the Yellow-striped flounder, Cresthead flounder, Marbled flounder, and Dark flounder. It is the only cogener to inhabit the Atlantic Ocean.
Adult winter flounder may grow as large as 70 cm and reach ages of 15+ years. Growth varies across their distribution, with northern populations generally growing slower than those at the southern end of their range.
